FEDERAL = Federal specifications

UNS	TYPE	AMS	ASTM	FEDERAL	CHARACTERISTICS
S42000	420	5621	A-276   A-314	QQ-S-763	420 is similar to 400, but the raised carbon content produces higher strength and hardness. Heat treatment to 50 RC min.
S42020	420F	5620	A-582	-	Free-machining variation of 420.
S42023	420F Se	5620	A-582	-	Similar to 420F, commonly used for forging.
